Doom gameplay shown at QuakeCon

id Software showed off a gameplay teaser of the new Doom game at QuakeCon 2014 but unfortunately it seems the footage has yet to make it online. IGN saw the demonstration and published some of the highlights. The new Doom game will be set outside a huge UAC research facility on Mars that's being invaded by the forces of Hell, it promises fast-paced combat against multiple enemies at once and old school gaming mechanics:

Hellknights, cyberdemons, revenants, mancubii, and other classic monsters were spotted throughout the demo.

Classic Doom weapons, including the fan-favorite double-barrell shotgun return. Plasma rifle, rocket launcher, and the good old chainsaw were also shown off.

Go fast. "Doom is not about about taking cover" said executive producer Marty Stratton.

Doom is powered by IdTech 6, and will be for PC, PS4, and Xbox One. They are "committed" to 1080P at 60 frames-per-second.

Wonderfully gory close range executions, including special ones for dropping down on enemies from above.

Revenants now have jetpacks and can hover about while firing rockets at you.
At least one weapon, the combat shotgun, has an alternate fire mode, which allows you to charge up and release multiple shells in rapid succession.

Sprinting, double-jumping and mantling are all possible, making for very fluid motion during combat.

Enemies can teleport in for old-school style ambushes

Dying results in a crazy fatality scene depending on what killed you a la Dead Space. Revenants rip your arms off and punch straight through your combat helment.

Old school mechanics. No reloading your clip, hold as many weapons as you want, health and ammo pick-ups etc. NO REGENERATING HEALTH.
